Abstract: A joint stabilizing apparatus having an expandable cylindrical housing is inserted into a circular hole drilled at a "loose joint" of a concrete slab that is to be stabilized against relative vertical displacement between adjacent slab sections. The hole is drilled downward into the concrete, centered on the plane of a lateral opening/joint in the concrete slab. The expandable housing comprises two rigid semi-circular housing halves, and the assembly is oriented inside of the circular hole such that the two housing halves are on opposite sides of the centerline of the lateral opening/joint. The housing halves are pushed apart by turning of a threaded bolt inside of the housing. Turning of the bolt causes two bilaterally symmetric wedge blocks to draw towards each other, and pressing the bearing surfaces of the wedge blocks against inclined surfaces inside of the respective housing halves. As the housing halves are pushed apart, the outside surfaces of the expandable housing engage the walls of the drilled hole and apply opposing horizontal compressive forces to the slab sections. Friction between the expandable housing and the concrete slab sections prevent the slab sections from vertically moving relative to each other. In other embodiments of the invention, the joint stabilizing apparatus is used to prevent relative motion between non-horizontal construction members, and between four adjacent slab sections separated by intersecting loose joints.

Abstract: A range of concentrations exists in which fermentation inhibitors derived from pretreatment of lignocellulosic feed stocks inhibit growth of lactic acid bacteria without affecting fermentive yeast. By optimizing levels of fermentation inhibitors to fall within this range, yeast fermentations of lignocellulosic biomass can be conducted under non-sterile conditions with ethanol yields comparable to those achieved under sterile conditions. Optimised inhibitor levels can be achieved by controlling the water/biomass ratio of a lignocellulosic biomass during and after pretreatment, for example by washing the fiber fraction of a previously pretreated lignocellulosic biomass with a pre-defined amount of fresh water or recycled process solutions. Crude extracts of liquid fraction or process solutions from pretreatment of lignocellulosic biomass can also provide an effective anti-baterial treatment for first generation starch fermentations.

Abstract: Disclosed is a wood preservative composition comprising micronized copper and copper-amine complex, wherein the copper component of the copper amine complex is from about 5% to about 50% by weight, based upon the total weight of copper in the composition. The copper amine complex serves to avoid wood surface 'chalking' that is otherwise attributable to the presence of micronized copper in copper-based slurries used to treat wood products. In addition, the copper-amine complex enhances the antimicrobial efficacy of the composition when used in wood treatment applications by facilitating cell wall penetration of the treated wood.
